HAND PRINTING DEVICE.

SPECIFICATION forming part of Letters Patent No. 772,352, dated October 18, 1904.

Application filed March 31, 1904.

To all whom it may concern.-

Be it known that I, CHARLES F. HALLER, a citizen of the United States, and a resident of Cleveland, county of Cuyahoga, and State of Ohio, have invented certain new and useful Improvements in Hand Printing Devices, of which the following is a specification.

My invention relates to improvements in hand printing-rollers; and the object of my improvement is to equip a contrivance of this class in such manner as to enable printing therewith in difierent colors in one operation namely, by drawing the rollers over the paper to be printed.

A further object is to so equip and construct an article of this kind as to enable its use by inexperienced persons with satisfactory results. I attain this object in a contrivance constructed substantially as illustrated in the accompanying drawings, in which Figure 1 represents a face view of said printing-rollers. Fig. 2 is a central vertical sectional view of the same. Fig. 3 is an end view of the same; and Figs. 4: and 5 represent transverse sectional views on line X X, showing the rollers in different positions.

A designates the frame of the device, being of open form, having the sides a a and back or ridge a, the latter carrying the handle E, which extends vertically therefrom. The sides a a are provided with openings .7) b to receive the trunnions of the printing-rollers B B and also with open slots 0 c to receive the trunnions of the inking-rolls C C, the latter being held within the slots by springs 0, carried by a shaft F, hereinafter described.

The rollers B B are of any preferred structure, having their faces provided with printing-surfaces and also with raised portions at their ends adapted to bear on the surface on which the stamping is to be placed. Each roller has a gear D, which coacts with a gear D, carried by the shaft F, said gears causing both rollers to move in unison, thereby insuring that during the movement of the device over the surface to be stamped the relation of the printing matter carried by each roller will be maintained, it being understood, of course, that the printing-surfaces of the rollers are relatively arranged initially to pro- Serial No. 200,936. (No model.)

duce the desired result in the completed stamp. For instance, one roller may contain thename of a company with a spaced line located therebelow and the designation of the oflicer whose signature is to be placed on the line, while the opposing roller will contain the facsimile of the signature. When the rollers are placed in position, they are relatively arranged so that when the device is moved along the surface to be stamped the signature will be printed in proper position relativeto the remaining matter carried by the other roller, this relation being subsequently maintained by reason of the gearing of these parts to move in unison. It should be explained that the rollers B B being arranged side by side the movement of the device over the surface to be stamped causes the printing-surface of the forward roller to first contact with the surface to be stamped, the printing surface of the second roller making its contact as it passes over that portion of the surface to be stamped which has already received the matter contained on the first roller. The rolls C C are intended to receive ink of different colors. For instance, one may have black ink, the other purple. In this manner'thematter on the rollers B B will be printed in the color carried by the roll C with which it is in contact and producing the eifect of printing in two colors.

In order that the movement of the rollers B B may be limited to prevent the printing of more than is intended or a duplication or partial duplication of the printing, a stop is provided which limits the movement of the rollers to one complete revolution. This stop comprises a slide H of substantially U shape, the arms extending parallel with the axis of the rollers,'the portion connecting the arms being located outside of one of the sides a, the arms extending through openings in the side. One terminal, a, coacts with a perforation j, formed in the gear D, the other terminal, g, being beveled and extending in close proximity to the beveled end of the spring-supported rod G, which extends axially through the handle E. The arm carrying the terminal g extends through an opening in an arm f, depending from the ridge or back a, and

carries a spring for normally maintaining the operative connection between the terminal 7? and the gear D. The upper end of the rod G extends beyond the end of the handle E, a spring normally maintaining said rod in a projected or inoperative position, said rod being held against rotation by a suitable pinand-slot connection. By'this construction it will be seen that when the parts are in position with the terminal c in engagement with the perforation j the rollers B B are held fixed against rotation. By moving the rod G downward the beveled faces of the terminal 9 and lower end of the rod G cause the slide H to be moved outward, thereby releasing the engagement between the terminal 71 and perforation j and permitting the rollers B B to be rotated by the movement of the device After the rollers have been partially rotated the release of the rod G by the operator permits the terminal 2' to contact with the face of the gear D in position where as the rotation is continued it will pass into the perforation under the action of the spring carried by the slide, the release of the rod permitting the necessary movement of the slide. In thus operating the slide H the particular location of the end of the rod G at the upper end of the handle E is of particular advantage, inasmuch as the face of the handle is free to be firmly grasped by the operator without respect to the slide or stop mechanism and without disturbing the same and for the further reason that it is locatedat such point as will permit the rod to be operated by the thumb of the operator without changing the position of the hand on the handle E and without necessitating the movement of the hand in any respect other than the thumb of the hand holding the device. The entire pressure desired may be initially placed on the device prior to the movement of the rod G and this pressure maintained during the movement of the rod and of the rollers. hile the release of the slide H fromthe action of the rod Gby releasing the latter from the pressure of the thumb will permit the terminal 9 to pass into its perforation j, thereby forming a stop to limit the movement of the rollers, such operation is dependent upon the operator releasing the pressure on the rod G. Should he fail to release such pressure, the rollers would continue to move, thereby permitting a duplication or partial duplication of the printing. To prevent such result, 1 have provided an auxiliary stop mechanism which will when the pressure on the rod G is maintained automatically stop the rotation of the rollers at a predetermined point. IVhen the rod G is released, this automatic stop mechanism is rendered inoperative, the stoppage of the rollers being obtained through the slide'H. This auxiliary stop mechanism is as follows:

The lower end of the rod G is provided with a pivotally-mounted latch 12, which extends downward and is adapted when the rod G is depressed to extend into the path of movement of a lug cl, carried-by the shaft F, said lug being located at a point. on said shaft to cause an operative contact with said latch when the rollers have reached their normal locking position. To permit the rotation of the rollers when the rod G is initially depressed, the latch 01, which has its movement limited by lugs p 2), carried by the rod G, is held by a spring 0 against one of the lugs 19, and thereby permitting the rod G to be depressed with the latch n behind the lug (Z. Upon the rotation of the rollers with the rod G depressed the lug (Z will pass into contact with the latch 91, these two parts then moving forward until the latch contacts with the forward lug p, when further movement will be prevented owing to the stopping of the movement of the shaft F. When the rod G is released, the latch is carried out of the path of movement and out of contact with the lug d, said latch moving pivotally, under the action of the spring 0, to the point where the depression of the rod G will pass it behind the lug cl.

From this construction it will be understood that the device is capableof printing in two colors and that the movement of the rollers is absolutely limited to one complete revolution, thereby preventing any liability of a duplication or a partial duplication of the matter being printed. Furthermore, to enable the operator to predetermine the exact position of the facsimile when printed I provide a rod 0* in front of the rollers and carry same in sockets s of the guide-rolls L. (See Figs. 1, 3, and 4.) As will be noticed, this rod r is set in advance of roller B, and its position is also rendered adjustable within the sockets s to suit various kinds of lettering 7': Z upon the rolls B B. The guide-rolls L also give a steady position to this printing device when and while same is rolled over the paper.

What I claim, and desire to secure by Letters Patent, is

1. In a hand printing device, a frame having a handle; a shaft mounted within said frame, independent printing-rollers carried by said frame and geared with said shaft, said shaft and rollers moving in unison; a stop carried by said frame adapted to coact with said shaft to limit the movement of said rollers, and means extending through said hans dle and operable at the upper end thereof, for releasing the engagement between said step and shaft.

2. In a hand printing device, a frame having a handle, a shaft mounted within said frame, independent printing-rollers carried by said frame and geared with said shaft, said shaft and rollers moving in unison; a stop carried by said frame and adapted to coact with said shaft to limit the movement of said rollers, said stop comprising a U-shaped slide having its arms extending parallel with said rollers, one of said arms having an operative contact with the gear of said shaft; and means extending through said handle and operable at the upper end thereof, for moving said slide to release the engagement between the terminal and gear.

3. In a hand printing device, a series of independent printing-rollers having fixed bearings in said frame geared to move in unison, a stop carried by the frame and adapted to limit the movement of said rollers, means for releasing said stop to permit the rotation of said rollers, and an auxiliary stop actuated solely upon the failure of the first-mentioned stop to limit the movement of the rollers.

4:. In a hand printing device, a series of independent printing-rollers geared to move in unison; means for normally retaining said rollers against movement, and mechanism for releasing said retaining means, said releasing mechanism limiting the movement of the rollers upon failure of the retaining means to oppositioned to prevent movement of the rollers beyond a predetermined position.

6. In a hand printing device the combination with. a series of independent printingrollers geared to move in unison, of guiderolls and an adjustable transverse rod, the latter being so adjusted as to serve as a guide for producing the printing in the allotted position.
